Rural landscape by Luke Howard with children playing by a cottage, c 1808-1811.

Watercolour sketch by Edward Kennion, with cloud studies by Luke Howard. This plate shows 'cumulostratus; as produced by the inosculation of cumulus with cirrostratus. Cirri above, passing to cirrocumulus.' Ordering and classification were important features of Enlightenment science. Fascinated since childhood by the weather, and clouds in particular, Luke Howard classified and named different cloud types between 1803 and 1811, providing sketches for these later illustrations. His work influenced many landscape painters of the Romantic era, including Turner and Constable. Although he was a pharmacist, his contribution to meteorology led to Howard being made a Fellow of the Royal Society in 1821. His terminology and symbols are still used today.
